Custom Home Plans

How Much Does It Cost?

Designing a custom home is a major investment—and we believe the pricing for your plans should be clear and predictable. That’s why we work on a flat-fee basis, with pricing based on project scope—not a percentage of your total construction budget.

Many architects charge 4–7% of the construction value for design services. At QuickenPlans, we offer transparent, fixed pricing based on what your project actually requires. No guesswork. No inflated fees.

What Affects the Cost?

Several factors influence the overall design and engineering cost of your ADU:

• Location: Local codes, HOA rules, and permitting complexity can all influence scope.

• Size & Layout: Larger homes or multi-level designs typically require more planning and coordination.

• Design Complexity:

- Straightforward builds with simple layouts are more efficient to plan.

- Custom layouts, premium features, or unique conditions increase design complexity.

• Construction Methods: Advanced techniques or high-end finishes may increase planning requirements.

• Site Conditions: Sloped lots, narrow parcels, or utility challenges may require additional planning or engineering.

What’s the Price Range?

Here’s a general breakdown of what to expect:

• Mid-size, straightforward homes – $25,000–$30,000

• Larger or more complex projects – $40,000+

This includes complete building design and structural engineering services, energy compliance documentation (if required), and a full permit-ready plan set. Site surveys, grading plans, or civil engineering (if needed) are not included.

Getting an Accurate Estimate

Every property and project is different. That’s why the best way to get a clear cost estimate is to book a consultation. We’ll review your goals, site details, and timeline—and provide a tailored proposal that reflects the real scope of your project.

Timeline & What You’ll Get

When planning a custom home, it’s important to understand the full scope—how long it takes and what’s included. At QuickenPlans, we balance thoughtful design with efficient execution, so your plans are complete, coordinated, and ready to move forward.

How Long Does It Take?

The design process is a true collaboration. We work quickly on our end while relying on timely decisions and feedback from you to stay on schedule. Here’s a general outline:

• First Concept Design:

After your design kick-off meeting, we’ll deliver your first concept iteration within 10–15 business days. This is the first time you’ll see your vision start to take shape.

• Full Plan Set:

Most custom home projects are completed in 4–6 months, depending on project complexity and communication pace.

What’s Included?

Deliverables may vary slightly based on your local regulations, but here’s what’s typically included in a full custom plan set:

• Floor Plan – Interior layout with room dimensions, doors, windows, and fixtures.

• Elevations – Exterior views from all sides, showing windows, rooflines, and finish details.

• Sections – Cross-sectional views that show how different levels and spaces relate.

• Roof Plan – Roof design with slopes, materials, and any skylights or special features.

• Basic MEP Layout – Placement of visible Mechanical, Electrical, and Plumbing fixtures.

• Construction Details – Key details like wall assemblies, connections, etc.

• Structural Drawings & Calculations (for structural remodels) – Foundation, framing, and structural specs, prepared and stamped by one of our in-house licensed engineers, ready for review by building officials.

• Energy Compliance Report – Required in many areas, this ensures your project meets current energy efficiency standards.
